I bought this 3 amp charger knowing it would take me a while to charge my 24Ah LiFePO4 battery. But even with 12.6 volts on the battery, it took about 9 hours for the red light on the charger to turn green and the battery to reach 13.4 volts. I use the battery in my kayak so I don't have to fully charge it right away. Overnight charging is fine. The info says it's for batteries up to 23Ah so I push it to charge my 24Ah. They make a larger 10 amp charger but I went with the cheaper one. I just have to be patient. It's new, so I can't comment on durability.
